vIVIEASURING ATTACHMENT FOR POWDER-BOXES.

SPECIFICATION forming part of Letters Patent No. 582,972, dated May 18,1897. Application filed February 6, 1897. Serial No. 622,332. (Nomodel.)

To all whom. t may concern.;

Be it known that I, SIDNEY FRANKLIN AUS- TIN, a citizen of the UnitedStates; residing at Brooklandville, in the countyof Baltimore and Stateof Maryland, have invented certain new and useful Improvements inMeasuring Attachments for Powder-Boxes; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

Myinvention has relation to improvements in bakingpowder box measuringattachments, and more particularly as an improvement on a device for thesame purpose, for which Letters Patent No. 540,345 were issued to me onJune 4, 1895.

The object of the improvement is to provide a simple, cheap, andportable measuring attachment of this class; and to this end the noveltyconsists in the construction, combination, and arrangement of the same,as will be hereinafter more fully described, and particularly pointedout in the claim.

In the accompanying drawings the same reference-characters indicate thesame parts of the invention.

Figure 1 is aperspective'viewof a powderbox embodying my invention.Fig.` 2 is a vertical section through the box. Fig. 3 is a detailperspective view ofthe registering rib and groove in the cover of thebox. Fig. 4 is a top plan of the cover with the disk mounted a shortdistance between the limit-points.

It is a well-known fact that the usual ingredients which compose abaking-powderas, for example, cream of tartar and bicarbonate ofsoda-will keep indefinitely when separate, but when combined to form abaking-powder will rapidly deteriorate unless herm'etically sealed. Myinvention provides a box for keeping these ingredients separated andmeans for withdrawing the proper portion of each ingredient, asrequired, to form a baking-powder.

1 represents a suitable cylindrical box or case provided with alongitudinal central partition 2, which divides the box into twocompartments 3 and 4.

5 represents a removable cover provided with a longitudinal V-shaped ribG, which engages a correspondingly-shaped groove 7 in the upper part ofthe box to insure the proper position of the cover of the box. Thiscover comprises a top or outside plate 8 and a diaphragm 9, arrangedparallel with and a short distance below the top plate.

10 represents a rotating disk mounted on a stud 12 between the top plateand the diaphragm.

13 represents a pin fixed in the edge of the disk 10 and extendingradially through a slot 14 in the rim of the cover, the length of theslot corresponding to about one-quarter of the circumference of the rim,and -it serves to limit the movement of the disk to that extent.

The disk is formed with two oppositely-arranged transverse pockets 15and 16, and correspondingly-shaped openings 17 and 1S in the diaphragm 9register with the pockets when the disk is at one end of its movement,and as these openings in the diaphragm are arranged one over eachcompartment it follows that if the box be inverted the powder in thecompartments will fall by gravity through the openings in the diaphragmand fill the respective pockets in the disk. While the box is still inthis position, if the'pin 13 be moved about one-half of the distance ofthe slot 14 the pockets in the disk are carried past the orifices in thediaphragm, and consequently the charge of powder in the pockets isseparated from the bulk of the box.

19 and 2O represent oriiices in the top plate 8, which are arranged at aright angle to the corresponding orifices in the diaphragm, and are alsoin line with the pockets in the disk when the latter is at the oppositeend of its stroke, so that the pockets havin g been filled, as abovedescribed, it is only necessary to move the disk to the end of itsstroke to dis- Y charge the powder into the iiour.

In some instances I make the disk with but one pocket to hold a certainpredetermined quantit-y, say a teaspoonful, and an undivided box. Thisconstruction will be found very convenient for the ordinary readymixedyeast-powder of commerce, as well as spices and other granular orpowdered substances nsed in the culinary art.

Various other modifications of my inven- ICO tion will readily suggestthemselves to those skilled in this art without departing from thespirit thereof.

Having thus fully described my invention, what I claim as new anduseful, and desire to secure by Letters Patent of the United States, 1s-

A combined measuring and mixing can comprising the cylindrical box 1,having the longitudinal partition 2, in combination with the removablecylindrical Cover 5, formed with a slot 14 in the rim thereof, andhaving its top plate S, provided with oppositely-disposed segmentalorifices 1E) and 20, and its diaphragm 9, formed with oppositelydisposedcorrespon din g segmental orifices 17 and 1S, located one on each sideof the partition 2 in the box, and at a right angle to the ori- Iiees inthe top plate, and the measuringdisl: 10 rotating in the Cover betweenthe top plate and the diaphragm, and provided with theoppositely-disposed segmental pookets 15 and 1G, and the operating-pin13,
